Title: Chummer or bait-distribution system
Inventor: MARGUTSCH STANILAUS S
IPC: A01K97/02
Filed: 1992-12-14
Abstract: ABSTRACT           A novel chummer or bait distribution system. The system is comprised of a ported tube which slides up and down over a weighted cylinder housing. When the chummer has been lowered to the desired depth, it is pulled upwards slightly so that water pressure on top of the cylinder releases a latch and allows the outer tube to drop by gravity. As the tube drops the resulting water pressure forces the bait to be distributed, via a port, into the surrounding water. Previous chummers were bottom opening; this side opening chummer with weighted base allows for rapid lowering into the water and for bait to be distributed at any desired depth.

Title: Camera apparatus
Inventor: ISHIZUKA SHIGEKI
IPC: G02B27/64
Filed: 1993-01-27
Abstract: A camera shake correcting apparatus includes a variable angular prism assembly, a microcomputer to produce signals for driving the variable angular prism assembly, prism actuators, vertical angle sensors, angular velocity sensors for detecting an angular velocity caused by the camera shaking, and damping coils. The variable angular prism assembly is driven by a signal obtained by subtracting detected results of the vertical angle sensors from detected results of the angular velocity sensors. A damping coil is used to produce rotational angular velocity signals so that a nonlinearity of the prism can be alleviated. The phase margin of the servo characteristic of the prism drive system is increased, so that the camera shake correcting apparatus can be generally independent of variations in values and dimensions that occur in mass-production manufacturing operations and free of dependency on temperature characteristics.

Title: Process for purifying an oxidation waste gas
Inventor: MODIC RUDOLF
IPC: F02C3/30
Filed: 1991-08-20
Abstract: Abstract The invention relates to a process for the purification of an off gas which originates from a reaction process operated under pressure  and  which  is  contaminated  with  aliphatic  and/or aromatic substances, by scrubbing the off gas. The off gas to be purified originates in particular from an oxidation process operated  with  oxygen-containing  gas,  for  example  from  the oxidation of para-xylene (p-X) with air by the so-called Witten DMT  process  for  the  preparation  of  dimethyl  terephthalate (DMT).            The off gas is subjected to purification by absorption under pressure, the absorbent consisting predominantly of an ester or of an ester mixture.  The ester or the ester mixture has a higher boiling point than the substances to be washed out.            The process preferably comprises the following main steps:   a)   Partial condensation of the substances to be washed out, at about 35-60°C; b)   Absorption  with  methyl  para-toluate  (p-TE)  or  with  a mixture of p-TE and methyl benzoate (BME); c)   Absorption with BME and/or methanol; d)   Absorption with water; e)   Combustion under pressure, if necessary with the supply of oxygen and combustible products.

IPC: H04W64/00
Filed: 1993-06-08
Abstract: REMOTE  POSITION  DETERMINATION                      ABSTRACT      A constellation of satellites which are distributed around the earth serves as a communications infrastructure that supports autonomous position determination and reporting of that position to a remote location.  Satellites continuously broadcast acquisition signals.  Position determining units are remotely programmed to activate upon the occurrence of an activation event.  If PDUs can capture an acquisition signal, then they engage in activities which lead to determining their position and they coordinate their communications with the requirements of the communications infrastructure.  To determine position, a location pulse may be transmitted on a regular schedule.  The location pulse is transported between a fast moving satellite and a PDU.  The movement of the satellite causes different location pulses to have different propagation delays and Doppler characteristics.  By analyzing changes in propagation delays and Doppler characteristics, a procedure determines a position for a PDU.
